IPv6, the next-generation Internet Protocol, is designed to replace IPv4 due to its larger address space and improved features. Configuring IPv6 on a network can seem daunting, but understanding the basics can help you set up a reliable and efficient IPv6 environment. In this blog post, we’ll walk through the essentials of configuring basic IPv6 […]

Imagine your internet connection is like a busy highway with cars, trucks, bikes, and pedestrians all moving in different directions.

National Research and Education Networks [NRENs] are expected to connect all R&E [Research & Education] community sites and institutions regardless of physical location or infrastructure presence. This expectation necessitates that the NREN think outside the box to create new and unconventional last-mile solutions. One innovative approach involves boosting the LTE (Long-Term Evolution) connectivity in regions

As IPv4 addresses become increasingly scarce, it\’s essential for Tier 3 ISPs like RENU to embrace IPv6. Here\’s why: Address Space: IPv6 provides an almost inexhaustible supply of unique IP addresses, ensuring that your network can accommodate the growing number of connected devices. Improved Security: IPv6 includes built-in security features like IPsec, which enhances data

For ISPs like RENU, ensuring high availability is crucial to maintaining uninterrupted services. Here are some strategies for achieving network redundancy: Redundant Internet Links: Establish multiple internet links from different providers or routes. Implement BGP (Border Gateway Protocol) for dynamic routing to automatically switch traffic to the backup link if one goes down. Load Balancing:

Network security is a top concern for Tier 3 ISPs like RENU, as cyber threats can disrupt services and compromise data integrity. Here are some essential practices to enhance network security: Firewalls and Intrusion Detection/Prevention Systems: Deploy robust firewalls and intrusion detection/prevention systems to monitor and filter incoming and outgoing traffic. Regularly update rule sets

In the world of computer networking, efficient bandwidth utilization is paramount, especially for small Tier 3 Internet Service Providers (ISPs) operating in regions like Africa. In this blog post, we\’ll explore some strategies for optimizing bandwidth usage in such environments, with a focus on the Research and Education Network for Uganda (RENU). Traffic Shaping and

In a network where Service Providers run customers’ VLAN traffic over their backbone network, there is a possibility of VLAN crushing if different customers use overlapping VLAN IDs. With Q-in-Q Tunneling Providers can segregate different customers’ VLAN traffic on a link (for example, if the customers use overlapping VLAN IDs) or bundle different customer VLANs

Virtual private LAN service (VPLS) multihoming enables you to connect a customer site to two or more PE routers to provide redundant connectivity. A redundant PE router can provide network service to the customer site as soon as a failure is detected. VPLS multihoming helps to maintain VPLS service and traffic forwarding to and from
